CLAUDE ZNOBLES, OF ST. JOHN, 'NEW BRUNSWICK, CANADA.

SAiS-HQHOLDER.

To all whom it may concern:

Be it known that I, CLAUDE Nonnns, a subject of the King of Great Britain, residing at St. John, New Brunswick, Canada, have invented certain new and useful Improvements in Sash-Holders, of which the following is a specification.

This invention relates to sash holders, and has for its object to provide certain new and useful improvements in this class of devices whereby a window sash :may be conveniently held at any desired elevation, and also conveniently released to permit of the window being raised or lowered.

It is a further objeot of the invention to provide a simple and inexpensive device which can be readily applied to a "window sash without making any alterations therein beyond recessing one of the stiles of the sash so as to accommodate the parts-of the holder;

The holder may be fitted to any ordinary window sash without requi-ring the employ- V out departing from the all ment of a skilled workman.

With these and other objects in view, the present invention consists in the combination and arrangement of parts as will be hereinafter more fully described, shown in the accompanying drawing and particularly pointed out in the appended claim, it being understood that changes in the form, proportion, size and minor details may be made, within thescope' oifthe claim, with spirit or sacrificing anyof the advantages of the invention.

In the drawings 2-Figure 1 is atrojnt elevation of the lower portion -of a window equipped with a sash holder 0f the present invention. Fig. 2 is an enlarged fragmentary view showing "the recessinthe window sash and the wedging or holding element in one of the recesses. Fig. 3 is an elevation looking at the edge of the window sash with the holder in place and in condition for lifting the sash. Fig. 4: is a cross-sectional view on the line 4-4. of Fig. 5. Fig. 5 is a view similar to Fig. 3 with the parts in the positions assumed in the closed position of the window.

Like characters of reference designate corresponding parts in each of the figures of the drawing.

For the purpose of illustrating the application and operation of the present 1nvention there have been shown in the accompanying drawing a window frame 1 and a window sash 2.

understood by reference :to Fig. 4': of the 1 drawing. The'back of the recess 3 is also recessed to form a seat a, which seat intersects the edge of the sash. The greatest transverse width of the seat l is at its middie, from which the width of the seatdecreases regularly in opposite directions :toward its ends. mental inshape and its wall 5 being an arc of a circle. if desired, the wall 5 maybe provided with a suitable lining 6, such, for instance, as rubber, felt, or the like. Within the seat 4 is a wedge element 7, preterabl-y a hard spherical body or ball, the diameter of which is greater than the greatest width of the seat l at its middle, so as :to projectsli-ghtly through the open side of the seat.

Located in the recess 3 is a slide-8, preferably in the form of a rectangular metallic plate which is shorter than the recess and capable of sliding endwise therein. lhis plate has the same width as the recess (Band is provided with anupper pin 9 anda lower pin '10 working in the seat 4:, one above and one below the wedging member 7, and de signed to movethe wedging member in the seat :as will be hereinafter explained.

For the purpose of holding the slide 8 in place, there is a face plate 11 countersunk inth'eiace of the stile of the sash and fixed in place by means of suitable fastenings 12. This face plate is provided with a longitudinal slot 13 through which projects the shank 14, carried by the slide 8, and in turn carrying at its outer end a knob or handle 15.

In the closed position of the window, the wedging member 7 will be at the middle of the seat a andwill be supported by engagement with the back of the seat and the adjacent edge of the window frame. Any attempt to lift the window from the exterior of the building will result in a wedging of the member 7 and thorizedopening of the window. the window from the interior of the building, the knob or handle 15 is grasped and Preferably the seat 4 is segthereby prevent unau- L To open pushed upwardly, whereby the lower pin 10' will lift the wedging member 7 into the widest middle portion of the seat 4, and thereafter the window may be opened by pushing upwardly upon the knob or handle 15 as the shank thereof will be at the upper end of the slot 13. lVith the window sash in an elevated position, if the handle or knob 15 is released, the sash will more downwardly a short distance until the wedging member 7 has become wedged between the back wall of the seat i, and the adjacent edge of the window frame. To lower the sash, the knob or handle 5 is pulled downwardlyfso as to push the wedging member 7 intotthe middle widest'portion of the seat so as tov free the sash and permit ofit being moved 1 freely downward.

.l/ ith thec window sash in its lowermost position, the wedge member 7 will be at the middle of the seat or recess a: because it will be: supported byireason of its engagement with the back of the recess and the adjacent edge of the windowframe. The slide 8 will also be at vits lowermost position with the pin 9 at. the top of the wedge 7 and the pin 10' in engagement with the back of the seat or recess 4. When the handle is manipulated. to lift the window sash, the slide 8 will move upwardly until the shank l4: strikes theupper end of the slot 13, and the c upper end. of the slide strikes the upper end of the'recess 3, whereby the movement of the slide is limited, and the lower pin 10 will bein engagement with the bottom of the wedge and the upper pin 9 in engagement with the back of the seat 4. In other words, the length of the slide 8 and the length of the recess 3are proportioned to properly limit the endwise play of the slide 8, and the pins 9 and 10 are located upon theslide in proper positions to respectively bring the" wedge into the middle portion of the seat 4. I

As bestshown in Fig. 4 of the drawings,

the window frame is provided'with a strip 16 of felt, rubber, metal or other material, which is preferably set into the frame in a position to be engaged by the wedge member 7. The wedge element 7 has been described as a hard spherical body or ball. However, as a hard element will dent or otherwise mar the window frame, I contemplate making the member oi rubber or other suitable material having suilicient elasticity to produce the desired effect without injuring the window frame.

While the invention has been described in connection with a window sash, it is to be understood that it also may be used in connection with elevators, draws, sliding and swinging doors, fanlights, rolling desk tops, etc.

Having thus described the invention, what is claimed and desired to be secured by Letters Patent, is:

The combination of a window sash having a seat formed in one of the stiles thereof, that side of the seat adjacent the window frame being open, and the opposite side of the seat being inclined in opposite directions from its middle toward the ends of the seat, a wedging member in the seat and having a width exceeding the greatest width of theseat whereby the member is in constant engagement with the seat and window frame, and a slide mounted upon the stile and provided with upper and lower projections lying at opposite sides of the wedging member for contact therewith to move said wedging member in opposite directions into the widest portion of the seat, said projections being spaced to an extent greater than the diameter of the wedging member whereby to permit movement of the wedging member between the projections.

In testimony whereof I afiix my signature in presence of two witnesses.
